A couple more Steam Deck beta updates that are still highly regular and it looks like they finally fixed the issue preventing the Steam Deck from rebooting properly which is not listed but has been an issue for us since a few updates ago.
General
Fixed viewing and closing a news event partially blocking mouse and touch input on the window.
Desktop Mode
Added a toggle in notification settings to turn on/off sounds for non-critical notifications.
Fixed taking a screenshot playing two sounds.
Rearranged the notifications settings page and made some controls respond to changes in the global settings.
Fixed overlay windows showing in a pinned state when the overlay is activated for some games (e.g. Warhammer: Vermintide 2). Desktop Mode
Fixed showing a black screen at startup if the startup location was set to something prohibited by Family View.
Removed incorrect date display on some DLC hovers.
Fixed the tops of some context menus not being interactable if they overlap the title bar.
